How to add it to your site
- Copy the code Use the copy button in the Embed code box so nothing is lost to line wrapping. It is a single iframe tag and it does not need anything else.
- Open the page you want it on In WordPress add a Custom HTML block, in Wix use the Embed HTML element, in Squarespace use a Code block, and on a hand-built site paste it straight into your HTML.
- Paste and publish The widget appears immediately. If you see an empty space instead, your editor has stripped the iframe tag, which the HTML embed guide explains how to work around.
- Adjust the look if you want to Add the parameters in the table below to the iframe URL to change the theme, the accent colour or the height. Nothing needs to be configured on our side.
Customisation options
| Parameter | Values | What it does |
|---|---|---|
theme | auto, light, dark | Default follows the reader's own system setting, so the widget looks right on a dark site and a light one without you choosing. |
accent | Six hex digits, e.g. accent=1A56DB | Recolours the header bar and the primary button to match your brand. |
header | 1 or 0 | Set to 0 to hide the title bar when your page already has a heading above the widget. |
breakdown | 1 or 0 | Set to 0 to hide the calculation breakdown for a more compact block. |
corners | 1 or 0 | Set to 0 for square corners if your design has no rounding anywhere else. |
width | full | Removes the 520px maximum so the widget stretches to its container. |
Parameters are added to the iframe URL as a normal query string, for example
/embed/crypto-position-size-calculator.html?theme=dark&accent=1A56DB&header=0. The
widget builder lets you set all of them visually and hands you the finished code.
Why embed the Crypto Position Size Calculator
Crypto moves far more than a major forex pair, so the same risk percentage produces a much smaller position, which surprises most beginners. The widget sizes the trade from account balance, risk percentage and stop distance, and handles the wide stops crypto needs without rounding to lots. Crypto exchanges, trading communities and tax blogs that touch crypto can all embed it.
What the widget calculates
Position sizing works the same way in crypto as anywhere else: risk a fixed percentage, divide by the stop distance, and the size follows. What changes is the stop distance, because daily ranges in crypto are several times those in major currency pairs.
A 1% risk rule with a 2% stop on EUR/USD and the same rule with a 12% stop on an altcoin produce very different position sizes. Using a forex-sized position on a crypto stop is the most common way accounts are damaged.
The embedded version keeps the inputs and the result. The full Crypto Position Size Calculator on TradeAnswers adds worked examples, the method behind the numbers and a long FAQ.
Who this widget suits
Trading education sites
Drop it into a lesson on risk management so readers can test the concept immediately instead of reading the formula and moving on.
Finance blogs and newsletters
A working tool in a post gives readers a reason to return to that page, which tends to help both time on page and repeat visits.
Course and membership pages
Embed it in a module on money management. It works inside most course platforms that allow a raw HTML block.
